Submitted in the Senate, considered, and agreed to without amendment by Unanimous Consent. (consideration: CR S6; text: CR S6)
The President pro tempore of the Senate is the second-highest-ranking officer in the legislative branch, serving as the Senate's presiding officer when the Vice President is absent. This position has existed since the founding of the Senate and is filled through a formal resolution voted on by all senators. The role carries significant ceremonial and procedural authority, including the ability to recognize senators seeking to speak and to break ties on procedural matters. Traditionally, the position goes to the longest-serving member of the majority party, though the Senate retains the constitutional power to elect any sitting senator to the office.
This resolution directs the Senate to elect Charles E. Grassley, a Republican senator from Iowa, as President pro tempore of the Senate. The election occurs through a simple majority vote on the resolution itself. Grassley, first elected to the Senate in 1980, is the longest-serving Republican senator at the time of this resolution's passage in January 2025. The resolution formalizes the Senate's choice through the constitutional process outlined in Article I of the Constitution, which grants the Senate the power to elect its own officers.
The resolution takes effect immediately upon passage and agreement by the Senate. No additional funding or implementation timeline is required, as the position and its duties are already established under Senate rules and constitutional authority. Grassley assumes the title and responsibilities of President pro tempore, which include presiding over Senate sessions, maintaining order during debates, and serving in the presidential line of succession. The election does not affect existing Senate operations, committee assignments, or legislative procedures, though it does formally establish the Senate's leadership structure for the 119th Congress.
The President pro tempore becomes the second person in the presidential line of succession, after the Vice President. The office carries formal procedural authority over Senate operations, including the power to recognize speakers and manage floor debate. This election formally establishes the Senate's leadership structure for the 119th Congress and clarifies the chain of command for legislative operations.
Charles E. Grassley, the newly elected President pro tempore, gains expanded procedural authority within the Senate. All 100 U.S. senators are affected by the establishment of formal leadership hierarchy. The Vice President's office is affected insofar as the President pro tempore becomes the designated successor. The general public is indirectly affected through changes in how the Senate conducts its legislative business and maintains order during proceedings.
